Rare bird documentation form for Golden Eagle near Waukon, 1978	Field notes	Birds--Identification Ornithology Rare birds	1978-03-26	1978-03-27	Rare birds documentation form	Rare bird documentation form for a Golden Eagle near Waukon in Allamakee County, IA on March 26, 1978.	Schaufenbuel, Joseph P.	Golden Eagle	Waukon	Ten miles North of Waukon, on Highway 76, Allamakee County, Iowa	The general area under the soaring bird was a bluff, covered mostly with Oak, Maple, Birch and scattered Junipers.

I realize how difficult it is to tell these thrushes apart. I have not seen any Hermits in six days of birding over the last two weekends. We have had three warm nights with south winds that have brought early migrants to Iowa. I records [sic] six 1st, 2nd, or 3rd early dates the last two days in southeastern Iowa. In spite of this, I tried to make this bird into a Hermit Thrush. I believe I saw the tail enough times and at enough angles to determine that it wasn't rufous. The face pattern did not in any way suggest to me that this was a Swainson's I find that the density of breast streaking is difficult to judge even on specimens. \| The original documentation form event lasted from 07:45:00/07:48:00.
